When your pipe has dried, place it in the oven (DO NOT PREHEAT) and turn the oven on to 350 degrees. Your pipe will need about one hour to bake. The clay is done baking when brown specks appear on it.

IMPORTANT: To avoid the possibility of your clay breaking due to thermal shock, DO NOT open the oven during the entire baking cycle. Turn off the oven and allow it to completely cool before removing your pipe. If you cannot see through your oven door to determine whether the clay has finished baking, set a timer for one hour, and then turn off the oven and allow it to cool for another hour before checking on your project. This should be efficient time for your clay to bake.
